The one that I have is labeled as the TWIN V102, however, if you look it up on the Sunpak site at [ http://www.sunpak.com/sunpri.html ], the Sunpak catalog # for the TWIN V102 is "ACC-M1013-01" - which is described on their site as the Twin V102 Rapid Charger. This is the model I have.

I did a search on the web for the TWIN V102, and nothing comes up - however, when I search for the ACC-M1013-01 catalog #, I get it for sale at various sites such as [ http://www.batterymart.com/merchant2/merchant.mv?Screen=CTGY&Category_Code=digitalcamera ] for about 39.95. If you look closely at the picture of the unit, you will see the word "CANON" in each battery compartment - just like it says on the model I have.
